OMNIS – Karl Fischer titration easier and safer than ever

OMNIS is Metrohm’s new, fully integrated solution for water content determination with volumetric Karl Fischer titration. Determining water in samples has never been more convenient, safer, and easier.

Safe: All chemicals handled in a closed system, no contact with reagents.

Easy: The water content determination starts automatically with the sample injection.

Convenient: the Karl Fischer reagent is supplied and removed automatically.

Safe KF titration with OMNIS

With OMNIS, Karl Fischer titration is safer than ever. Contact with toxic reagents and solvents is eliminated:

No contact during reagent exchange thanks to 3S Liquid Adapter.

All reagents contained in a closed system.

Used reagent discarded automatically

Automatic titration cell filling and emptying

Contact-free reagent exchange

Exchange reagent bottles safely with OMNIS. You no longer need to open bottles with hazardous liquids. Simply snap the Liquid Adapter onto the cap of the reagent bottle. This closed handling system establishes a safe connection between the reagent and your OMNIS Titrator preventing accidental contact with hazardous liquids.

Full traceability of reagents

When the Liquid Adapter connects the reagent bottle to your OMNIS Titrator, OMNIS reads all information on the reagent from an RFID chip in the bottle cap and checks this information against the specifications of your method. This fully automated check prevents errors and provides full traceability of your results.

Easy KF titration with OMNIS

OMNIS makes volumetric water content determination easier than ever. This system takes care of a lot of the tasks that you used to do manually:

It starts the titration automatically

After measurement, the used sample is discarded automatically

The cell is prepared for the next determination automatically

More on easy titration

Automatic titration start

Your OMNIS system starts the titration automatically when you inject the sample – Never waste any sample again because you didn't push the button.

Used sample removed and cell prepared for next analysis

Thanks to the OMNIS Solvent Module, the used sample is removed from the titration cell and discarded fully automatically.

The Solvent Module of your OMNIS Karl Fischer titrator also prepares the cell for the next measurement automatically.

Fast KF titration with OMNIS

Remove lid – titrate – close – repeat – all done automatically

Streamline work in your lab with OMNIS automation. With the addition of a sample robot to your OMNIS Karl Fischer titrator the system becomes almost 100% autonomous – just fill it with samples regularly and press start.
The complete analysis is then carried out automatically, including opening and closing of the sample beakers.

Easy and fast sample preparation (time saving up to 25%)

Samples are protected from environmental influences

Automatic KF Dis-Cover lid handling

Work stations working in parallel (40% faster than sequential determination)

More on fast titration

Faster sample prep, better results

Thanks to OMNIS KF Dis-Cover, you can save up to 25% of your time for sample preparation compared with other systems. In addition, the automated Dis-Cover closure ensures that all samples are treated identically, which improves reproducibility and result accuracy.

Higher throughput

Run more samples in the same time thanks to work stations running in parallel. With just one additional work station, you will save 40% of the time compared with sequential determinations.

Less solvent required

Save solvent by automating water determination. The OMNIS Sample Robot makes it possible to use just 12 mL of solvent per sample.

And there's more: some highlights of the OMNIS analysis platform

Get the better user experience: The OMNIS software

The OMNIS analysis platform runs on an innovative and intuitive software. The software supports you with functions such as prompts, embedded help, systems checks, and status indicators.

More samples? Simply upgrade

Start with an OMNIS Sample Robot with one work station and simply add another one to the existing system to increase your throughput dramatically. With a system with four parallel work stations, you will save up to 60% of the time compared with a system running with a single work station.

What is volumetric Karl Fischer titration?

Karl Fischer titration is a method for moisture determination that is specific to water. As opposed to other methods, such as drying ovens or infrared lamps, Karl Fischer titrators determine the actual water content in a sample, whereas other methods determine all volatile components that evaporate under the influence of heat.

One of the main benefits of Karl Fischer titration is that the water content determination typically takes only a few minutes, compared to up to several hours for drying techniques.

Karl Fischer titration is a well-established and widely applied analytical method. For example, it is the reference method mentioned in many national and international standards applied in all industries.
